The Razorspine Rattler's Constriction Ability

[Jinn]

The Constriction ability is worded: This model gains  to disengaging strikes. Razorspine Rattler's also have the Wicked ability, so they deal damage with disengaging strikes.

My question is do they get  to the disengaging strike's damage flip as well as the attack flip?

[Adran]

No

To perform a damage flip the model dealing the damage flips the top card of its
deck and compares the card’s value to the damage flip chart below. A model may
Cheat Fate on a damage flip with the same restrictions as any other flip.
Damage flips are often the result of a duel. They do not gain any of the modifiers
(Fate or otherwise) that were applied directly to the duel that might have caused the
damage flip. Effects that modify the damage flip will state that they do so specifically. (page 52)
